At some angle/rendering distance change walls' rendering breaks

Cannot reproduce. Do they render correctly at different angles? Did you place them in a specific order?

Actually its a strange combination of the two.
It seems to happen randomly, and after a few ticks/block updates it gets fixed.

Will investigate further for a way to reproduce this precisely.

Okay so a way to reproduce it, at least on my side is:
Place a few or many walls together (can be any variation) while doing, change the  render distance to 32 close, remove these blocks, place a few more and change it back to 8 and it should happen.
